And what is God's Standard Criteria for evaluating what "the fact of actual errors" is and His Perspective on "variations and errors", for which we have Scripture Warrant, from God Himself?
There are at least two different computer-based KJV texts that are printed in over 30 post-1980 editions of the KJV, and each of them has a different set of variations and errors.
Notice the various books in the New Testament 'quote' these two verses in Jeremiah, from Jeremiah 31:33 and Jeremiah 31:34;
this gives us a beginning view on God's Standard Criteria for evaluating what "the fact of actual errors" is and His Perspective on "variations and errors", for which we have Scripture Warrant, from God Himself;
(and we're not even considering the different spellings of names, from the Old Testament to the New Testament, etc., which we take for granted, even though they can be quite different looking.)
Jer 31:33; "For this is the covenant that I will make with the house of Israel after those days, declares the Lord: I will put my law within them, and I will write it on their hearts. And I will be their God, and they shall be my people."
John 6:45; "It is written in the Prophets, ‘And they will all be taught by God.’ Everyone who has heard and learned from the Father comes to me— "
Rom 11:27; “and this will be my covenant with them when I take away their sins.”
Heb 8:10; "For this is the covenant that I will make with the house of Israel after those days, declares the Lord: I will put my laws into their minds, and write them on their hearts, and I will be their God, and they shall be my people."
Heb 10:16; “This is the covenant that I will make with them after those days, declares the Lord: I will put my laws on their hearts, write them on their minds,”
...
And as we see Jeremiah 31:34 quoted in the New Testament;
Jeremiah 31:34; "And no longer shall each one teach his neighbor and each his brother, saying, ‘Know the Lord,’ for they shall all know me, from the least of them to the greatest, declares the Lord. For I will forgive their iniquity, and I will remember their sin no more.”
John 6:45; "It is written in the Prophets, ‘And they will all be taught by God.’ Everyone who has heard and learned from the Father comes to me—
Rom 11:27; “and this will be my covenant with them when I take away their sins.”
Heb 8:11; "And they shall not teach, each one his neighbor and each one his brother, saying, ‘Know the Lord,’ for they shall all know me, from the least of them to the greatest.
Heb 8:12; "For I will be merciful toward their iniquities, and I will remember their sins no more.”
Heb 10:17; "then he adds, “I will remember their sins and their lawless deeds no more.”
They are all valid and accepted in their own state, without much question, in the final results. They show God's expectable criteria, for judging 'errors' and variants.
